TLDR
In the present experiment a chequerboard was flashed at a standard ISI of 2000 msec, with occasional flashes occurring early at ISIs of 500, 1000 or 1500 msec, suggesting that temporal uncertainty is an important factor.About:

The N1 wave of the human electric and magnetic response to sound: a review and an analysis of the component structure
Risto Näätänen,Terence W. Picton +1 more
TL;DR: It is concluded that at least six different cerebral processes can contribute to the Nl wave of the human auditory evoked potential, and that they often last much longer than the true N1 components that they overlap.
Journal ArticleDOI
Brain generators implicated in the processing of auditory stimulus deviance: a topographic event-related potential study.
TL;DR: The results showed that, in all cases, the negative wave elicited by the deviant stimuli showed the highest amplitudes over the right hemiscalp irrespective of the ear of stimulation or the direction of attention, and this asymmetric potential distribution could be attributed to the sum of activities of two sets of neural generators.

Characterization of N200 and P300: selected studies of the Event-Related Potential.
Salil H. Patel,Pierre N. Azzam +1 more
TL;DR: The authors present a synthesis of current understanding of two components of the ERP, P300 positivity and N200 negativity, appearing 300 ms and 200 ms post-stimulus in both normal and pathological states.
Journal ArticleDOI
Synergistic effect of combined temporal and spatial expectations on visual attention.
TL;DR: Event-related potentials revealed the presence of individual modulatory effects attributable to spatial and temporal expectation as well as synergistic effects indicative of an interaction of the two, likely to play a critical role in directing attention to the reappearance of a temporarily occluded moving target.
Journal ArticleDOI
Temporal attention enhances early visual processing: a review and new evidence from event-related potentials.
TL;DR: An ERP experiment aimed to observe a modulation of early visual processing by using a perceptually demanding task, such as letter discrimination, and shows, for the first time, that targets appearing at attended moments elicited a larger P1 component than unattended targets, which suggests that temporal orienting of attention not only modulates late motor processing, but also early visualprocessing when perceptually demands tasks are used.

Early selective-attention effect on evoked potential reinterpreted ☆
TL;DR: The ‘Hillyard effect’ was explained as being caused by a superimposition of a CNV kind of negative shift on the evoked potential to the attended stimuli rather than by a growth of the ‘real’ N 1 component of theevoked potential.

Two varieties of long-latency positive waves evoked by unpredictable auditory stimuli in man.
TL;DR: Two distinct late-positive components of the scalp-recorded auditory evoked potential were identified which differed in their latency, scalp topography and psychological correlates.

Early selective-attention effects on the evoked potential: a critical review and reinterpretation.
TL;DR: On the basis of the subsequent set of experiments, the conditions and limits of the existence of the auditory 'N1 effect' are now quite clear and this finding has been extended to somatosensory and visual modalities.
Journal ArticleDOI
Stimulus deviance and evoked potentials
TL;DR: The comparison of these brain-wave sequences to those elicited by the same stimuli in reading subjects led to the conclusion that in detection conditions, deviant stimuli elicit two overlapping sequences of brain events: exogeneous and endogeneous.
